EYEGLASSES.

Application filed October 1, 1927. Seria1 No..223,372.

to cover any kind of frame for supporting lenses before the eyes of a wearer.

Among the features of my invention is the provision of simple, light, neat, effective and durable means for firmly and securely holding eye-glasses in place on the head of a,

5 wearer with a minimum of discomfort.

In those forms of devices embodying the features of my invention shown in the accompanying drawings Figure 1 is a view in front elevation; Fig. 2 is a View on an enlarged scale, taken as indicated by the line 2 of Fig. 1; Fig 3 isa View on an enlarged scale, taken as indicated by the line 3 of Fig. 1; Fig. 1 is a vertical sectional view of an optional rubber bulb for. producing a vacuum; Fig. 5'is a view in front elevation of a modified form; Fig. 6 is a view on an enlarged scale, taken as indicatedby the line 6 of Fig. 5; Fig. 7 is a view in front elevation of another modilfiedform'; Fig. 8 is a'view in front elevation of still another modified form;'F1g. 9

is a view on an enlarged scale, taken as viewed by line 9. of Fig. 8; and Figs. lOand 11 are views in front elevation of additional modified forms.

Among the features of my invention is the provision of improved vacuum or suction cups, together with means for producing and maintaining suction therein. Another feature of my invention is the use of parts of the frame of the eye-glasses for affording air communication with the suc-' tion cups. Another featureof my invention istheprovision of means for automatically producing continuous suction in the cups over a space of time, thus giving the wearer 'ust the eye-glasses before losing the suction. I V V 7 Another featureof my invention is the provision of-spring means in. connection with the frame, said spring means oper ating the suction producing means.

Other features and advantages of my invention will appear more fully as I proceed with my application.

Inthe device shown in Fig. 1, indicates a frame of the usualform supporting the lenses 11, 11. 12,12, indicate rubber cups or flanges inset in the frame and adapted to bear against the'sides of the nose of the wearer. Air communication is afforded from these cups through the passage 13 in g the frame 10to the suction producing means 14, shown in Figs. 1 and 3 as a cylinder with a piston 15pressed outwardly by a spring The piston 15 is provided with a spring valve controlled air by-pass 15 of the usual form. A pushing the piston 15 inwardly to expel air from the cups-12. Upon release of the butfinger button' 17 is provided for 1 ton 17, the spring'16 urgesthe piston outwardly to withdraw'air from the cups 12 to produce a partial vacuum therein to cause the same to adhere to the sides of the nose.

The vacuum cylinder 14 is preferably provided with arestricted air. outlet 18 or a restricted air inlet 19, as shown, to slow down the movement of the piston 15 even though v the cups 12 be not in contact with the nose. By this construction, it will be seen that even though the button 17 is released,-the

cylinder 14 willcontin ue to withdraw air v slowly from the cups 12, thus giving the wearer an appreciable time to adjust the glasses in position and set the cups 12' se-.

curely in place, so thatthe vacuum when produced will not be quickly lost.

In Fig. 4 isflshownan ordinary rubber which may be used for producing a vacuum instead of the cylinder 14. This bulb also may be provided with a restricted air inlet 19?, as shown, to slow the "action.

'In Figs. 5 and 6, I have shown another form of device in which the eye-glass frame is provided with an additional curved bridge member 20 extending from lens to lens; This member is 12, 12 adapted to be placed against the forehead of the wearerf The member 20 is provided with an air'passage 13 leading to a suction vcylinder 1 1, as shown in Figs.v 1 and 3. In the device shown in Fig. 5, the vacuum cylinder 14 is connected to the frame 20 by means of a flexible tube 21-.

' The device shown in Fig. 7 issubstan tially' the same as that shown in Fig. 5, ex cept that the bridge member 20 is somewhat resilient or springy so that in addition to the vacuum cups 12", the bridge member 20 may be slightly straightened to separate the nose clamps 21 WVhen. released, the nose clamps 21 will assist inholding the eyeprovided. with two rubber cups r at 23. 12 (see Fig. 9),

.27 which has a pivotal connection at 28,

with the lens frames 22. It will be seen that pivoting the lens frames 22 on the pivots 23 to separate the nose clamps 21 will compress the vacuum cylinders, and that upon releasing, the cylinders will operate to produce a partial vacuum in the cups 12? against the forehead, and at the same time c the nose clamps 21 the nose. v

In the form of device shown in Fig. 1O, I provide two vacuum cups communicating with a double vacuum cylinder 31,

will grip the sides of having two pistons operated by the finger clamps 32. Air communication is afforded between the cups 30 and the cylinder31 embodiments of my invention, it is through the passage 33 in the frame.

In the form shown inFig. 11, the bridge member 34-. is slightly resilient, and instead of providing the finger clamps 32, as shown in Fig. 10, I let the piston rods 35 bear As the frames 37 are bent slightly upwardly to the positions indicated by 37, the pistons in the vacuum cylinder 38 are compressed so that when the frames are released the pistons will separate to produce a vacuum in the cups 39. A release of the lens frames will also cause the bridge member 34; to bend back into its normal shape, thus causing the cups 39 to press more securely against the sides of the nose. I

WVhile I have shown and described certain to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention.

WhatI claim as new and desire to secure by Letters Patent, is:
